In MapServer, I want to show a polygon WMS layer (watersheds). I want to show the boundaries (outlines) of the polygons as a non-transparent thick line. And I want to show the inside (fill) of the polygons with 50% transparency. Is this possible?
I tried to set OPACITY 50, but this changes the transparency of both the outline and the fill. The second option I tried was to set TYPE line, but this shows the fill as complete transparent and the GetFeatureInfo no longer works by clicking inside the polygon.
What I would like to get, is: The outlines of my polygons have 0% transparency. The fill of my polygons has 50% transparency.
